Referring to the drawings wherein like that numeral 5 generally refers to the pre- 4the cylinder 6.

the conical shaped 0' andjinto this cavity'V 15 descends the funnel p5 like'constructon I to `communicate coupled as at 22 to "elongated tubular handle 23 which is pronuinerals designate likeparts, it can be seen v groove 2 6, circuinventin'g the opening 25.799

ferred forni of the invention, which includes i" the cylinder 6` providedwith 'a closed head 7 at itsupper end, and a lslightly de riding lower end 8 through which there atively large lopening l9 (the saine being a drain 50' opening) extends to communicate the cavity 10 kto theI atmosphere. Y i Numeral' 11 represents a' horizontal partiftion'above the cavity 10 which supports the upstanding barrel 12, the latter being open 5 5 atits'uppe'r end and spaced laterally from Depending into the barrel t12 land in s ac'ed relation thereto from the head 7 is t 'e nipple 13 provided with a" conical e0 shaped opening lther'ein opening through thelower end thereof.; Numeral 15 re re.b

sents a cavity with which the upper en of enng 14 communicates at thelower endof the bore 1,7. I

y The" nipple 18 projects laterally from' the head `7 andffhas a duct 19 extending longitudinally therethrough and `into head-l0 with the cavity 7 It will now be seen that the entire device is constructed ofl some suitable, but` preferably high grade' resilient material Asuch asl vulcanized 'rubber'. 75

Thepump is to be-engaged onto the 'faucet 20, with the faucet nozzle firinly fittingy into the bore '17g The hose 21 is coupled to the nipple 18. This hose 21 is the inner end of the,

vided with a relatively broad head 24 at its 'outer end,.the handle and head being constucted'in the general nature of a toothbrush except that the handle and head are` 85 preferably of some suitable light metal with 'the lheafl 24 provided' with an elongatedl openin 25 therein. y 'i The ead '24 is provided with an internal at the interior ofthe head and this groove QG is to receive the flange 27 extending around the perimeter of the resilient insert generally referred to by numeral 28. This insert which maybe ot several different forms includes the roughened outer surface Q9 and the upstanding bevelled boss 30 through which the opening 3l ext-ends. This openingr 8l extends` completely through the bore and the insert so that when water v1s passing downwardly through thepunip a jvacnnm is created in the tube 21eecting a suction through the opening of t-he boss :l0 of the insert, so that all particleso'foods and other foreign matter are removed from .between the teeth and from between the teeth and the gums of the patient.Y The insert is preferably of composite material having soine polishing ingredient distributed therein. f

Numeral 3Q generally refers to a slightly its face a roughened brushing porti-on and also having on its face at one end of said brushing portion a tubular projection the inner end of which is in communication with the interior of the hollow handle. and the outer end of which is open whereby in the use of the brush the teeth and gums will'be subjected simultaneously to a brushing action and a suction action.

In testimony whereof I ailix my shgnat-urie.v

EARL DONALD SMITH.

modified form of the invention (that vis the y pump ifeature), the same including a substantial-ly egg-shaped body- 33 provided i i with circumferentially extending enlargements 34 at the end thereof. The upperend of the body 34 has an inwardly extending y bore 35. gradually decreasing inwardly in diameter to receive the nozzlenf the faucet and imbedded 4in the body 33 and circumventingr this bore 35 is a reinforcing band 36.

y Numeral 3i' represents a cavity into which depends the nipple 38 having an upwardly rei ucing opening 39 therein communicating at its upper end with thc cavity 40 in the body 33. Depending into this cavity 40 is the funnel-like dependency 4l ,while extending from the cavity 40 is a duct 4 which i also extends through the lateral nipp e 43 on the body Numeral 44 represents a horizontal partition in the lower portion of the'cavity 37 through which the small ducts-35 extend. This partition 44 supports the upstanding barrel 46 into which the lower end portion ol` the nipple 48depc-nds. On the lower end of the body 33 below the duct45 is a downwardly tapering spout 4i' also constructed of thtI resilient material of the body 33.

Manifostly, suction will be created in the saine mannerwith the use of the device generally referred to by numeral 32.

While the foregoing specification sets forth the invention in speciiic terms, it is to be understood that numerous changes in the shape, size, and materials may be resortedvto without departing from the spirit and scope f of the invention as claimed hereinafter.

I claim:

As a new. article of manufacture, a tooth i 'and gum brush comprising a hollow handle adapted to be connected to a suction device,

and a brushhead carriedyby the handle and I formed of resilient material and having on les
